Short story taking place on a toroidal planet or moon involving flying. We can do this because the SVG cannot access the HTML document it's embedded into and so cannot "see" the other SVGs on the page. They do indeed, however, for this particular project I want something that ships as light as possible, and as light and as powerful as jQuery and D3 are, it would still mean downloading an entire library just for the sake of appending elements to an SVG, whereas this entire project (so far) has 21 lines of JavaScript. Just hand chosen artisanal links. It's fair to say that, when it comes to generating SVG with JavaScript, we can no longer say, "It only works in the browser.". webdesigner & webdeveloper, free-lancer, mainly working on
